For once I knew straight away what I wanted to do for Ancient Greece, beautiful orange and black pottery. Inspired from this image of Olympians. I think one guy is about to compete in the long jump, but he also looks like he is raking leaves! Over a base of orange polish, I painted with black acrylic paint. In some areas where I had made a mistake I had to scratch the black paint off, so this probably was not a good choice of medium. Once it is dry you are stuck with it.
